What is the 'false positive error rate'?

The false positive error rate refers to the proportion of emails that may be incorrectly blocked. The goal is to keep the rate as low as possible in order to prevent mistakenly blocked email and reduce administrator work. Hexamail Guard typically has a rate of less than 1 in 1000 upon initial installation, and with the use of automatic whitelists, this can be reduced much further over time.
